They are not the same object, of course (altough the threading.Event
object relies eventually on a mutex implemented using CreateEvent). But in
this case both can be successfully used; of course, having the Python
object a more "pythonic" interfase (not a surprise!), it's easier to use.
The same example modified using only a threading.Event object (and a few
messages to verify how it runs):
import threading
from win32api import OutputDebugString as ODS
class workingthread(threading.Thread):
def __init__(self, quitEvent):
self.quitEvent = quitEvent
self.waitTime = 1
threading.Thread.__init__(self)
def run(self):
while not self.quitEvent.isSet():
ODS("Running...\n")
self.quitEvent.wait(self.waitTime)
ODS("Exit run.\n")
import win32serviceutil
import win32event
class testTime(win32serviceutil.ServiceFramework):
_svc_name_ = "testTime"
_svc_display_name_ = "testTime"
_svc_deps_ = ["EventLog"]
def __init__(self, args):
win32serviceutil.ServiceFramework.__init__(self, args)
self.hWaitStop = threading.Event()
self.thread = workingthread(self.hWaitStop)
def SvcStop(self):
self.hWaitStop.set()
def SvcDoRun(self):
self.thread.start()
self.hWaitStop.wait()
self.thread.join()
if __name__ == '__main__':
win32serviceutil.HandleCommandLine(testTime)
